I'll be going to Nashville in a couple of weeks to help out my SIL who will be there for a weeklong training for her job. During the day she will be gone and I'll have DS (7 mos) and her babe (8 mos) to play with! I'm looking for suggestions for places to go out with 2 babies like nice parks or gardens or cool local shopping... maybe a neat flea market? I plan to borrow, rent, or buy a double stroller.
